Personally, I very much enjoy looking back over things written awhile, or even years, back. It can be unpleasant, and maybe you want to shake your head at times, but the process of creation involves growth and development.
I believe when any artist starts out, there might be a tendency for 'self-indulgence,' though I'd rather think of it as taking chances, absorbing influences, and learning. To a certain degree, it's even important to allow for a little indulgence, otherwise our work becomes too polished and inhibited, in my opinion.
If you choose to share any of your early work, and based on my limited experience with this forum so far, you will find an audience and people who appreciate it.
Or you can simply choose to keep those writings, possibly "borrowing" selections from them for other pieces, or shaping them into new ones.
